I am taking over maintenance of my in-ground 37000 gallon salt water pool with a chlorine generator. I intend on following this site's instructions and the first recommendation is to determine my salinity level and adjust it to be slightly over what is recommended by the generator's manufacturer. My issue is I have been able to find solid recommended test kits on this site but have not been able to locate the ideal salinity tester. Does anyone have a recommendation? Test strips vs drops?
